jlebleu [1] filed a deletion request for qlcplus-plugin-ola [2]: The OLA plugin for QLC+ is now built only if the OLA library is installed on the system. That's why this package is not useful anymore. The user - in waiting the integration into the official repo maybe! - just have to install or not the ola package before building qlcplus. Thanks for deleting it! [1] https://aur.archlinux.org/account/jlebleu/ [2] https://aur.archlinux.org/pkgbase/qlcplus-plugin-ola/
